[PATCH v2 2/6] gpg-interface: use left shift to define GPG_VERIFY_*

[Christian Couder <christian.couder@gmail.com>]

In "gpg-interface.h", the definitions of the GPG_VERIFY_* boolean flags
are currently using 1, 2 and 4 while we often prefer the bitwise left
shift operator, `<<`, for that purpose to make it clearer that they are
boolean.

Let's use the left shift operator here too. Let's also fix an indent
issue with "4" while at it.
